Indicates whether the DNS resolution is supported for the VPC. If
enabled, queries to the Amazon provided DNS server at the
169.254.169.253 IP address, or the reserved IP address at the base
of the VPC network range "plus two" will succeed. If disabled, the
Amazon provided DNS service in the VPC that resolves public DNS
hostnames to IP addresses is not enabled.

You cannot modify the DNS resolution and DNS hostnames attributes in
the same request. Use separate requests for each attribute.
